  • Cheat Sheet: Decoding Mineral Processing

    Gravity. Gravity separation is a term that covers several kinds of mechanical separation of metal from host rock. Since most metals are reactive and occur in oxide or sulfide combinations, this is mostly used for gold, which is unreactive and more often found in its pure metallic form. The key is that gold is much heavier than most rock.
